I have an '07 Passat as you might have noticed. It has 84000 something miles. Lately, it's been shaking while accelerating. My mechanic suggested I change the spark plugs and coils. I got that done and the car was fine. That was about a week ago. Today I was driving and it started shaking again, but a lot less violent, I guess you can say. It only happened when I was in 5th or 6th gear and at 2000 or so rpm. So, any ideas what that might be?
